Compatible HP Pavilion Models

This 120W AC adapter replaces the original power supply for HP Pavilion dv7-7171er, dv7-7174ef, dv7-7174sf and dv7-7175sf laptops. It delivers the correct DC voltage and current those models require. Buyers needing a charger for a different HP series or a higher-wattage unit will not be served by this part.

Input Voltage Range and Safety Limits

The adapter accepts 100V to 240V at 50 or 60Hz, so it works on mains supplies worldwide without a voltage switch. Built-in protection guards against short circuit, overvoltage, overcurrent and internal overheating. The 120W output ceiling means it cannot power laptops that demand a larger brick.

Straightforward Swap with One Common Pitfall

Installation is a simple case of unplugging the old brick and connecting the new one; no tools or software are involved. The most frequent error is ordering this adapter for a Pavilion model that looks similar but carries a different part number. Verify the exact model label on the laptop base before purchasing.
